- This article is about the Codex of Ezio Auditore da Firenze. You may be looking for the Codex of Altaïr Ibn-La'Ahad.
The Prophet's Codex was a codex written by Ezio Auditore da Firenze, Mentor of the Italian Assassins, detailing some of the most important events in his life. One such event was his meeting with Minerva in the Vatican Vault, whose speech he wrote down in great detail.
By the 21st century, the Prophet's Codex was located in the hidden library of Ivan the Terrible beneath the Bolshoi Theatre in Moscow. Daniel Cross, a Templar agent, infiltrated the library, after he had posed as a replacement for the Assassin guarding it. Following this, he opened the codex and read Minerva's speech to Warren Vidic via his earpiece, before taking it with him back to Abstergo and killing the Assassin sentry.
- The box that contained the Prophet's Codex appeared the same as the decorative casing for the Codex Edition of Assassin's Creed: Brotherhood.
